Abstract: An example automatic gain control (AGC) circuit includes a base current-gain circuit having a programmable source degeneration resistance responsive to first bits of an AGC code word. The AGC circuit further includes a programmable current-gain circuit, coupled between an input and an output of the base current-gain circuit, having a programmable current source responsive to second bits of the AGC code word. The AGC circuit further includes a bleeder circuit, coupled to the output of the base current-gain circuit, having a programmable current source responsive to logical complements of the second bits of the AGC code word. The AGC circuit further includes a load circuit coupled to the output of the base current-gain circuit.

Abstract: Methods and apparatus are described for a differential active inductor load for inductive peaking in which cross-coupled capacitive elements are used to cancel out, or at least reduce, the limiting effect of the gate-to-drain capacitance (Cgd) of transistors in the active inductor load. The cross-coupled capacitive elements extend the range over which the active inductor load behaves inductively and increase the quality factor (Q) of each active inductor. Therefore, the achievable inductive peaking of the load is significantly increased, which leads to providing larger signal swing across the load for a given power or, alternatively, lower power for a given signal swing.
